WIRE-BARBING MACHINE.

SPECIFICATION forming part of Letters Patent No. 297,472, dated April22, 1884. Application filed August 27, 1883. (No model.)

Zo aZZ whom it may concern.-

Be it known that I, PLEASANT A. TERRELL, a citizen of the United States,residing at Grinnell, in the county of Poweshiek and State of Iowa, haveinvented a new and useful Improvement in lVire Barbing Machines, ofwhich the following is a specification.

My invention relates to wire-barbing machines, and more particularly tothat class in which a two-pointed-wire barb is applied to one strand offencewire, and said strand is twisted with a plain wire to producebarbed cable fence-wire; and the invention consists in the novelconstructions, combinations, and arrangement of parts, hereinafter fullydescribed, and specifically pointed out in the claims.

Figure l is a plan View of my improved machine. Fig. 2 is averticallongitudinal section on line 3 g of Fig. 1. Fig. 3 is a verticalcross-section on line ax of Fig. 1. Fig. 4 is an elevation of thebarb-feeding mechanism, looking from the opposite direction to thatshown in Fig. 3. Fig. 5 is a detail plan view 2 5 of thebarb-cutting andbarb-coiling devices, as hereinafter more fully described. Figs. 6 and 7are enlarged views of the barb-coiling device attached to and rotated bythe twisterframe. Figs. 8 and 9 are like views of the 0 barb-coilingdevice, which may be mounted 011 the end of the twister-frame journal,and operated at a different speed from the twister, as hereinafter fullydescribed. Fig. 10 is a vertical longitudinal section, showingcoilingwheel 71, in a modified form, mounted on the twister, and securedthereto by suitable clam ping-pieces, so that it may be rotated at anysuitable speed, by a gear-wheelsecured on the main driving-shaft.

In Fig. 1,A A is a skeleton frame employed as a bed-plate, supported bysuitable legs, B B, and on this bed-plate are mounted the barbfeedingmechanism, the barb-coiling and ca bling mechanism, and the shafting foroperat- 5 ing the same, also the mechanism for feeding forward thefence-wires at regular intervals.

0 is a standard attached to the bed-plate,

and forms a support for the fixed cutting-tool o, and for the wire-guidecl, employed to guide the barb-wire from the barb-feeding device to'from the barb-wire.

its proper position with reference to the cut ting-tools and the mainfence-wire.

O is a cap secured to O, and in connection with the latter forms abearing for the rockshaft a. Through O and G, as shown in Fig. 2, thereis provided an opening, q, in which a hardenedsteel wire-guide, q, issecured to guide the strand of wire which is to be barbed.

The barb-feeding mechanism consists of the eccentric a secured 011 themain drivingshaft a, the eccentric-straps c the arm 0 the lever c",pivoted to sliding block a at c, the flange c on said block, theguide-rods c o, and the skeleton frame or standard 0, rigidly attachedto the bed-plate. The operation of 6 the barb-feeding mechanism is asfollows: The barb-wire is passed through openings in the standard 0 cand into the wireguide (I, thence forward on a curved line, as indicatedby dotted line in Fig. 1. Vhen main shaft a revolves, the eccentricoperates the arm 0 and draws the lower end of lever c in toward thecutting-tools. XVhen the lever has oscillated a short distance, theupper end comes in contact with the barb-wire, and clamps the same 7 5firmly against the flange c. As the movement of the eccentric continues,the block a", together with the barb-wire thus held, is carried forwardon the rods 0 c and the barb fed in adistance as required to form abarb. WVhile so the barb is being coiled 011 the fence-wire and beforethe barb-wire is severed, the eccentric throws the lever back and freesthe upper end The lower portion of the lever will now engage the end ofa set-screw, a, secured in a lug projecting from and made integral with0 and then forces the sliding block a back to its original position,ready to repeat the movement described. observed that the free movementof lever c allows the sliding block to be at rest for a short time atthe end of each thrust of the arm 0 and by increasing or diminishingthis -period of rest, by the set-screw c, the throw of l sliding block0, and consequently the length 9 5 of the barb, may be regulated asdesired. Sliding block 0 reciprocates in a line at right angles to thedirection of the passage of the I main fence-wire, and the opening inthe guide through which the barb-wire passes is slightly 10o It will becurved, to direct the barb-wire across the main wire at an obliqueangle, so that the free end of the barb-wire, as it is being coiledaround the fence-wire, will not impinge upon that portion of thebarb-wire which extends from the main wire back to the cutting-tools.

The movable cutting-tool o is secured in a head, If, made integral withshaft to, and is operated by oscillating the shaft by cam-wheel 12,secured to main driving-shaft a, through the cam-groove, stud, androller b and crank 21. When the lower end of the crank-arm is carriedout by the cam, the upper cutting-tool is oscillated inward and downupon the barbwire. As the motion continues, the barbwire, is severed andthe free end of the barbwire rests upon the upper end of the lowercutter, and the barb attached to the fence wire and just severed iscarried a short distance down in front of the stationary cuttingtool,and is free to advance forward toward the receiving-reel. v v

R is a rotating twister having hollow j ournals at each end, adapted topass the barbed wire, mounted in bearings g 9, over the bedplate. I

S is a spool mounted in the axis of revolution of the twister-frame, andsecured in position by a bolt, 8, and supplied with proper tension bypressure between the head of the bolt on one side and springs s s on theother side, in the usual manner.

r a 9" r a" are guide-wheels employed to direct the barbed strand aroundthe spool of plain wire, and to guide the same through the hollowjournals of the twister. The twister is rotated by the gear-wheels m andm the former secured on the main shaft a, and the latter on the forwardend of the twister.

h is a barb-coiling head attached to the rear end of the twister by acap-screw, as shown in Fig. 1. As the twister is rotated, thebarbcoiling lug h at the proper time engages the end of the barb-wireprojected across the fence wires, and carries it around the fence-wire.As the process of coiling the barb upon the fencewire continues, thefree end of the barb-wire is gradually shortened until the end projectsfrom the fence-wire just sufficient to form a barb. It will then passfreely through the opening in the end of the coiling-wheel. When it isdesired to place the barbs very close together on the fence-wire, it isdesirable to give the coiling-head amore rapid motion than the twister.I then employ coiling-wheel h as modified in Figs. 9 and 10, instead ofh as shown in Figs. 2, 6, and 7, and secure it to the end of the twisterby the annular groove and flanged caps 76', as shown in Figs. 9 and 10,and rotate the wheel by a gear-wheel, on the main shaft a. The mainwires are twisted into a cable near the forward end of the twisterimmediately after passing guide-wheel r, and are carried forward atregular intervals by the feed-drum 01*, mounted on shaft a secured inbearings attached to the bed-plate. a is a short shaft mounted in abearing, T, secured to the bed-plate, and carries a gear-wheel, m andcam-wheel n. This shaft is rotated by gear-wheel m on main shaft athrough an, its mating gear. Cam n is employed to rotate the drum atregular intervals as required to advance the main wires.

or is a wheel securely attached to the bars of the drum, and has on itsface a series of pins and friction-rollers equidistant from each other.0am n has a-groove adapted to engage one of these pins at a time,andaflange adapted to rotate the wheel a distance equal to the pitch ofthe pins at each revolution of the cam.

Drum n consists of a series of arms, each arm having a toothed wheelpivoted thereto and allowed to rotate on the pivot. A cam, 1 is placedon shaft a", but prevented from rotating thereon by an arm, 10, rigidlyattached to the bed-plate. This cam is arranged to engage the toothedwheels 1?, and, as they pass around under the shaft a to rotate them,respectively, through an arc equal to the pitch of theteeth. Thecable-wire passes once around this drum, resting injthc notches of thewheels 1?, and, by reason of the rotary motion given said wheels,whenthe barbed cable comes up on the inside of the drum next to the twisterit will not come in contact with the advancing cable, but will lie inthe adjacent notches of wheels 1? and pass freely forward to thereceiving-spool. The receiving'reel is attached to a distributing-shaft,a", secured in suitable bearings, and operated in the usual manner, anddriven by a belt andlfianged pulleys, as shown in Fig. 1. As I make noclaim to this device, and it is well known in the art to which myinvention pertains, no further description is here necessary. Thebarb-wire and the wire which is to be barbed may be mounted uponbrackets secured to the bedplate,or on independent supports, as desired.

Having now fully described my invention, what I claim as new, and desireto secure by Letters Patent, is-

1. The barb-feeding mechanism consisting of the eccentric 0", arm 0lever c, and sliding block 0 and means for operating said device,substantially as described.
